John Carmack recently joined Oculus VR to serve as their chief technology officer, but remained at id Software. However, Carmack found working two jobs quite difficult, and has officially announced his resignation from the Doom and Quake developer.

While id software has always been a forerunner in advanced technology and engine development, it is that very technology that is making it harder for the studio to continue to purse the creation of mod tools and easily moddable games, id studio director Tim Willits said.

QuakeCon 2013 is returning to Dallas on August 1-4, and if you can't wait to reserve your space for your computer at the free event, Bethesda is again offering special packages when it opens up pre-registration on April 15.

Bethesda has officially announced QuakeCon 2013, with the massive bring-you-own-computer event returning to Dallas this year on August 1-4. Perhaps this will be the year when Doom 4 comes out of "Bethesda mode."

While the next generation of consoles will likely represent a significant jump in computational power, Carmack believes that next-gen games will still target 30 frames per second, much like this generation.
